Steps followed:

Workbench 6.3 86x 
Windows 7 PRO 64x
Access 2007-2010

Procedures followed:
Open Database Migration

Start Migration

Source Selection
•	Database System: Microsoft Access
•	DSN: Set to Access DB


Target Selection


Fetch Schemas List


Reverse Engineer Source


Source Objects
*	All

Manual Editing
*       No errors, no changes made


Target Creation Object
*      Create schema in target RDBMS


Create Target Results
*      Clicked next

Goes to next screen (Data Transfer setup) and shows error. When clicking “Next->” and progressing to the “Data Transfer Setup” an error message comes up “Error – Unhandled exception: unknown attribute ‘getOS’” if “Next->” is clicked after closing this error then the following error is shown “Unhandled exception: list index out of range.”. The Schema for the DB is created and all tables and possibly all attributes added however the data is not imported.

Please let me know if any further information is needed. (Similar to closed and unresolved bug #76647)

Completely following migration steps from mysql tutorial:

Have the same problem with the same symptoms on Windows 8.1 using MySQL Workbench 6.3 32-bit version.  SCHEMA is successfully migrated, but data is not.

Same for me. MySQL Workbench 6.3 CE, WIN 7 pro 64bit, Access 2010 64bit.
Not only no data is migrated; also the copymigrateddata script is not generated.

... worked before switching to MýSQL Workbench+Office 2010 to 64 bit. 32bit all was OK.

Fixed as of the upcoming MySQL Workbench 6.3.4  release, and here's the changelog entry:

When migrating from Microsoft Access, the "Data Transfer Setup" step would
fail and throw the following exception: "Error - Unhandled exception:
unknown attribute 'getOS'". In other words, the tables were created but
the data was not migrated to MySQL.

Thank you for the bug report.

have exact same problem with win 7 Ent ver.6.1 and Office 2010 32 bit ver.14.0.7. so when would be next release?

I was experiencing this bug as well migrating from Access 2010 32 bit to MySQL Workbench 6.3.3 32 bit.

The only way I was able to work around it was to uninstall Workbench and reinstall an older version. Using 6.2.4 I was successfully able to perform data transfer and complete migration.

I was experiencing the same problem here, but I upgraded to workbench 6.3.4 32 bit and the problem was gone.
